David J. Petersen developed an ASCII-friendly transcription of these systems called SLIPA. Several of these systems can be transcribed using a notation developed by William Stokoe (“STOH-kee”), who developed cheremes (“KEE-reems”) to study them. (10[1]-5[1])Judy Kegl studied one of these systems that spontaneously arose (10[1])in Nicaraguan (10[1])schools. (10[2])One (10[1])of (10[1])these systems (10[1])named (10[1])for the town of Chilmark eventually developed (-5[1])into a now extinct system once used on Martha’s Vineyard. (10[1])Thomas (10[1])Gallaudet (10[1])co-founded a university that uses the American form of these (10[1])systems, (10[1])which uses finger spelling (10[1])for proper names. For 10 points, name this form of communication often used by the deaf. ■END■ (10[1])
